Whether knowingly or not, these headlines promote a false narrative that China wants the world to believe. As an example of complex psychological warfare, the narrative aims to weaken the will of the Japanese public and the international community at large to defend Taiwan against a future Chinese attack. To prevent the weakening of deterrence, it is necessary to set the record straight regarding Japan’s policy towards Taiwan.

The 1972 Japan-China Joint Communiqué

The previously cited news reports mischaracterize a comment made by Prime Minister Takaichi, who told lawmakers, “The Japanese government’s basic position regarding Taiwan remains as stated in the 1972 Japan-China Joint Communiqué, and there has been no change to this position.” Specifically, she is referring to paragraph 3 of the 1972 communiqué: “The Government of the People’s Republic of China reiterates that Taiwan is an inalienable part of the territory of the People’s Republic of China. The Government of Japan fully understands and respects this stand of the Government of the People’s Republic of China, and it firmly maintains its stand under Article 8 of the Potsdam Proclamation.”

Importantly, the communiqué does not say that Japan “affirms,” “recognizes,” “endorses,” or “agrees with” the viewpoint of the People’s Republic of China (PRC), the communist regime that governs the country today. The communiqué states only that Japan “understands and respects” the PRC’s position.

When the United States established diplomatic relations with the PRC, it used similar language. Paragraph 7 of the 1979 U.S.-PRC Joint Communiqué states, “The Government of the United States of America acknowledges the Chinese position that there is but one China and Taiwan is part of China.” In this context, the word “acknowledges” performs the same function as the phrase “understands and respects” does in the 1972 Japan-China Joint Communiqué.

A key legal distinction lies in whether a government uses the word “recognize,” which then constitutes formal acceptance of a claim’s legal validity. Japan and the U.S. both stated that they “recognize” the PRC as the “sole legal government of China.” By recognizing the PRC as the sole legal government of China, Japan and the U.S. were adopting a “One China” policy.

A crucial aspect of the “one China” policy adopted by both Japan and the U.S. is that neither recognizes the PRC’s claim that Taiwan is a part of China; they merely take note of the PRC’s position. Where the American and Japanese policies differ is Japan’s insistence that it “firmly maintains” its stance under Article 8 of the 1945 Potsdam Declaration. Unpacking the meaning of Japan’s reaffirmation of Potsdam requires a review of multiple related declarations and treaties.

Shimonoseki to Cairo to Potsdam

Several treaties and declarations over the last century have shaped how the international community manages the Taiwan situation. Following the First Sino-Japanese War, China’s Qing government ceded, “to Japan in perpetuity and full sovereignty,” the islands of Taiwan and Penghu, as stated within the 1895 Treaty of Shimonoseki.

Fast forward to before the end of World War II, U.S. President Franklin D. Roosevelt, United Kingdom (UK) Prime Minister Winston Churchill, and Republic of China (ROC) President Chiang Kai-shek issued the 1943 Cairo Declaration, promising the return of territories like Taiwan and Manchuria to China.

At the time, the PRC did not exist. The ROC government replaced China’s Qing government in 1912 and continued to govern China until it was forced out by the Communists in 1949, at which point it took refuge in Taiwan, Penghu, and various other minor islands along the Chinese coast.

Days before the end of the war, the major allies of the U.S., the UK, and the Soviet Union held the Potsdam Conference and issued the Potsdam Declaration, preparing the terms of Japan’s surrender. Article 8 of the 1945 Potsdam Agreement states, “The terms of the Cairo Declaration shall be carried out and Japanese sovereignty shall be limited to the islands of Honshu, Hokkaido, Kyushu, Shikoku and such minor islands as we determine.”

Following the devastation from the atomic bombings, Japan signed the Instrument of Surrender at the end of World War II, agreeing to “carry out the provisions of the Potsdam Declaration in good faith” and “take whatever action may be required…for the purpose of giving effect to that Declaration.”  Japan transferred administrative control of Taiwan and Penghu to the ROC in 1945. Only a few years after the end of World War II, civil war broke out between the ROC and the PRC on mainland China, leaving Japan no opportunity to formally cede the islands to either rival government. Although the ROC continues to govern those islands to the present day, it never acquired legal sovereignty over them. This is why Taiwan’s status is still often described as “undetermined.”

An International Matter

The Cairo Declaration cannot be implemented as originally intended because the ROC no longer governs China, and even if it did, Japan no longer has the legal capacity to transfer sovereignty. In short, Japan has never recognized Taiwan as part of China. Since 1972, it has acknowledged the PRC’s position without endorsing it, while reaffirming its postwar obligation to comply with the terms of Potsdam and Cairo.

As part of re-establishing relationships with the allies, Japan renounced “all right, title, and claim” to Taiwan and Penghu without designating a recipient through the signing of the 1951 San Francisco Peace Treaty. Neither the ROC nor the PRC governments were invited to participate, nor were they even mentioned within the treaty.

The San Francisco Peace Treaty is the latest legal document to leave Taiwan’s status unresolved, transforming it into an international problem rather than a settled matter of China’s domestic sovereignty. Prime Minister Sanae Takaichi’s recent remarks reaffirmed Japan’s longstanding position, which is essentially a position of neutrality. Claims to the contrary misread the Japanese Prime Minister’s words and the legal history behind them.

Not Part of China: An Explanation of Japan’s Taiwan Policy was originally published on Global Security Review.

5GW includes information dominance and manipulation, social engineering, economic coercion, cyber sabotage, and hybrid influence operations. It thrives on ambiguity, exploiting vulnerabilities without traditional combat. In 5GW, the lines between war and peace are blurred. No declarations, no clear enemies, just a relentless assault on stability. The goal is not to conquer land or destroy armies, but to cripple a nation’s spirit, economy, and infrastructure from within.

One of the most potent asymmetric tools of 5GW is economic manipulation. Palau, a serene archipelago of over 500 islands, were untouched by war until 2017. Palau dared to reject Beijing’s “One China Policy.” This move sent shockwaves through its fragile economy in the form of economic strangulation. In a masterstroke of economic coercion, China’s state-backed tour operators erased Palau from the Web.

Travel agencies stopped selling trips. Online searches yielded no results. Palau’s tourism industry, which accounted for 45 percent of gross domestic product (GDP), collapsed. Hotels emptied, airlines shut down, and the once-thriving economy suffocated.

This was not an anomaly, but a pattern. In 2016, South Korea agreed to facilitate the American THAAD missile defense system. China retaliated not with weapons but with economic muscle. Mysterious “fire and safety” violations suddenly appeared in South Korean businesses across China. A nine-month ban on Chinese tourism cost Seoul $6.5 billion. Retail giants like Lotte crumbled, thousands lost jobs, and yet, no war was declared.

The more interconnected the world economy becomes, the more vulnerable nations are to economic blackmail. Even Venezuela, despite its fiery anti-American rhetoric, was bound to the US economy. In 2018, despite Washington branding Nicolás Maduro a dictator and Caracas calling the US a “white supremacist regime,” the two nations still had $24 billion in trade, a quarter of Venezuela’s GDP.

Yet, when Washington imposed sweeping financial sanctions, Venezuela’s economy shrunk by 35 percent in a single year. After all, the United States does not just impose sanctions; it controls the very financial system that runs the world. The US dollar is the bloodline of global trade, and those who defy it find themselves cut off from international markets, unable to access capital or even conduct basic transactions. However, economic warfare breeds resistance.

Russia and China saw the writing on the wall. Between 2017 and 2020, Moscow slashed its holdings of US Treasury securities from $105 billion to just $3.8 billion and shifted towards China’s Cross-Border Interbank Payment System (CIPS), sidestepping American financial hegemony.

The true commanding heights of global dominance lie at the intersection of technology, finance, and unchecked ambition. China is not just selling 5G networks, it is embedding itself into the nervous system of global communication. On the other hand, the US does not just dominate finance, it controls the SWIFT banking system, ensuring economic warfare is just a sanction away. Similarly, corporations do not just innovate, they monopolize, influence, and quietly dictate policy behind closed doors.

“Surge forward, killing as you go, to blaze us a trail of blood.” A battle cry? Indeed. Not from a general on the battlefield, but from Ren Zhengfei, the founder of Huawei, a company waging a war not just against competitors but against entire nations. Britain’s telecom networks are suspected to have Chinese backdoors.

Information is now what oil was in the 1970s, a critical commodity to be controlled. Today, data is the new crude, and the battle to monopolize its flow has already begun. Quantum computing, AI, and machine learning are the new oil rigs, and the nations that dominate these technologies will dictate the future. Unlike oil, information is easily stolen, manipulated, or even weaponized in ways no physical resource ever could.

The first lethal autonomous drone strike in Libya, recorded in March 2020, was a grim reminder of what is to come. A suicide drone, powered by AI, needed no human command—just a target. Fire and forget was the name of the game. Imagine the next phase: terrorist organizations deploying AI-powered swarms, able to strike with precision, invulnerability, and zero risk to human operatives. They would not negotiate, would not retreat, and would prove hard to stop.  

In a world where biological warfare is outlawed, the selective control of food, aid, and healthcare has replaced mass destruction with slow, calculated suffocation. Nations can now deny access to the very essentials of life to break their adversaries in a siege without walls and a war without battlefields. Over 40 percent of the world’s population faces water scarcity, and by 2030, drought could displace 700 million people. The Turkish-backed militias that had control over the Alouk water station in Syria in 2020 was a stark reminder—when resources are weaponized, suffering becomes policy.

Interestingly, the battle of perception is gaining momentum more than ever. In an era of clickbait headlines and disinformation campaigns, lies travel faster than truth. The Massachusetts Institute of Technology found that false news spreads 70 percent faster than real news. From the Soviet KGB planting the rumor in the 1980s that the US government created AIDS to modern deepfake propaganda, deception is the new artillery.

Even culture is not immune. Hollywood exported American ideals, Bollywood spread Indian influence, and K-pop turned South Korea into a global powerhouse. For instance, the Cold War was not just won by missiles, it was won when a West German band sang “Wind of Change,” which then became the anthem of the Berlin Wall’s collapse.

If hunger, water, and financial systems hare already weaponized, the next battlefield is clear—space and the seabed. Subsea communication cables are responsible for carrying 97 percent of global data traffic and are the arteries of the modern economy. They enable over $10 trillion in financial transactions every single day. Yet, these vital lifelines remain shockingly unprotected and are vulnerable to sabotage, espionage, and strategic disruption. A targeted attack on just a handful of these cables could cripple stock markets, paralyze banking systems, and sever military command structures—all without a single warship being deployed.

Meanwhile, the race for space dominance is accelerating. From $63.66 billion in 2024 to an estimated $74.4 billion by 2028, the global military satellite market is growing, fueled by the realization that power no longer lies in boots on the ground, but in eyes in the sky. Satellites provide precision-strike capabilities, secure communication, and real-time battlefield intelligence. The Pentagon warns that the US is already vulnerable, with China and Russia developing anti-satellite (ASAT) weapons.

In this realm, one can say that modern states wage wars without battlefields, where the goal is not to destroy but to subdue—crippling economies, infiltrating cyber networks, and manipulating narratives without a single shot fired. What is never openly begun is rarely officially ended. In 5th-generation warfare, silence is a weapon, perception is the battlefield, and survival means accepting that war never truly ends.
